Release Sylpheed 3.4.2 with GnuPG support

I have tested it and it works great. My only problem with using it is that I can't function without html viewing since so much of my email arrives as html. I looked at the options for plugins but that looks like a dead end. Thanks for the hard work, I am using it for triage then doing my reading and replying in Thunderbird.
